Super cool!!
I've been using my own solution since January. I'm on Linux, and can't use Aqua, Whipsrflow etc... So i made my own.
Recently cleaned it up and made it install friendly.

It's self-improving over time, runs on your local machine, and is generally decent software. 60% of my interaction with my PC nowadays is pure voice input.
This is text to speech, yours is speech to text. (But also thanks, your STT looks interesting)
